In modern steel structure engineering, the material standards and pipe manufacturing processes directly determine the safety and durability of buildings. EN 10219, as the technical standard for cold-formed structural hollow sections in Europe, combined with the S235JRH material grade, provides reliable strength assurance for various projects.
Standard Interpretation: Technical Requirements of EN 10219
EN 10219 is a technical delivery condition in the European standard for cold-formed welded structural hollow sections, applicable to structural hollow sections with circular, square or rectangular cross-sections. This standard stipulates that the products should be formed in the cold state and no subsequent heat treatment should be carried out, thus maintaining the original mechanical properties and dimensional accuracy of the material.
As the core material of this standard, EN 10219 S235JRH possesses excellent yield strength and welding performance, and is widely used in construction structures, bridge engineering and mechanical manufacturing fields.
The technological advantages of Helical Seam Pipe En 10219
Helical Seam Pipe En 10219 adopts the double-sided submerged arc welding process, with the welds distributed in a spiral pattern. Compared to straight seam pipes, it has the following advantages:
Uniform force distribution: The spiral weld distributes the stress evenly, making it more capable of withstanding internal pressure.
Flexible specifications: Steel strips of the same width can be used to produce steel pipes of different diameters.
Cost-effective: High utilization rate of raw materials, suitable for the production of large-diameter pipes
The circular structural hollow profiles supplied by our company strictly comply with the EN 10219 standard. They ensure uniform thickness and strong welds, meeting the strict requirements of various load-bearing structures.
